You can find my presentation from yesterday here.
I plan to publish the speaker notes soon, after I clean them up some.
The session schedule for MWLUG in Atlanta is now online. The conference is less than 4 weeks, and there is a very strong lineup of speakers. Many have been presenting in the Best Practices track at Lotussphere fo years, and this conference is well worth attending. The cost is only $50, and there are still inexpensive flights left. Registration is still open, as I write this.
I will present my session AD102 Break out of the box – Integrate existing Domino data with modern websites on Wednesday afternoon, starting at 4.30pm. Hope to see you in Atlanta!
David Leedy from Notes-in-9 just posted a video where he talks about the upcoming MWLUG conference in Atlanta in just over a month. As I wrote the other day, I will be speaking there. David is actually mentioning me and my session, and I am humbled by his nice words.
Hope to see you in Atlanta!
It is less than 7 weeks left until MWLUG, the Midwest Lotus User Group conference. This year the conference takes place in Atlanta, between August 19 and 21. During the three days there will be over 40 technical session and workshops on collaboration, receptions and networking opportunities, as well as access to experts of IBM solutions, both from IBM and other companies. The topics includes application development, system administration, best practices, customer buisness cases and innovation/future plans by IBM. Breakfast and lunch is included for two days as well. And all this for the cost of only $50 per person! The event takes place at Ritz-Carlton in downtown Atlanta. There is a block of rooms reserved at a special conference rate of $149.00 per night.
One of the sessions will also mark my personal debute as a speaker at a conference. I will present “Break out of the box – Integrate existing Domino data with modern websites” where I will talk about how to integrate websites built either within Domino or on other platforms with backend data that resides in a Domino database. I will talk about how you can build a modern looking website using tools like jQuery and Bootstrap and seamlessly integrate them with existing data on your trusty Domino server using JSON and Ajax. I will also provide plenty of example code ready for you to bring home and start playing with.
A number of IBM Champions will be presenting, as well as IBMers and other industry experts. So no matter your interest, I am sure you will find plenty of good sessions. I am sure I will have a hard time picking which sessions to attend!

Here is another little code snippet I want to share. I use it all the time in my Lotusscript-based Domino web agents, and I figured that other could benefit from it as well. It is just an easy way to check for and read the name-value pairs (arguments) passed from the browser to the web server by HTTP GET or POST calls.
Put the code below in a script library, I call it Class.URL:
%REM Library Class.URL Created Oct 9, 2014 by Karl-Henry Martinsson Description: Lotusscript class to handle incoming URL (GET/POST). %END REM Option Public Option Declare %REM Class URLData Description: Class to handle URL data passed to web agent %END REM Class URLData p_urldata List As String %REM Sub New() Description: Create new instance of URL object from NotesDocument %END REM Public Sub New() Dim session As New NotesSession Dim webform As NotesDocument Dim tmp As String Dim tmparr As Variant Dim tmparg As Variant Dim i As Integer '*** Get document context (in-memory NotesDocument) Set webform = session.DocumentContext '*** Get HTTP GET argument(s) after ?OpenAgent tmp = FullTrim(StrRight(webform.GetItemValue("Query_String")(0),"&")) If tmp = "" Then '*** Get HTTP POST argument(s) after ?OpenAgent tmp = FullTrim(StrRight(webform.GetItemValue("Request_Content")(0),"&")) End If '*** Separate name-value pairs from each other into array tmparr = Split(tmp,"&") '*** Loop through array, split each name-value/argument For i = LBound(tmparr) To UBound(tmparr) tmparg = Split(tmparr(i),"=") p_urldata(LCase(tmparg(0))) = Decode(tmparg(1)) Next End Sub %REM Function GetValue Description: Get value for specified argument. Returns a string containing the value. %END REM Public Function GetValue(argname As String) As String If IsElement(p_urldata(LCase(argname))) Then GetValue = p_urldata(LCase(argname)) Else GetValue = "" End If End Function %REM Function IsValue Description: Check if specified argument was passed in URL or not. Returns boolean value (True or False). %END REM Public Function IsValue(argname As String) As Boolean If IsElement(p_urldata(LCase(argname))) Then IsValue = True Else IsValue = False End If End Function '*** Private function for this class '*** There is no good/complete URL decode function in Lotusscript Private Function Decode(txt As String) As String Dim tmp As Variant Dim tmptxt As String tmptxt = Replace(txt,"+"," ") tmp = Evaluate(|@URLDecode("Domino";"| & tmptxt & |")|) Decode = tmp(0) End Function End Class
It is now very easy to use the class to check what values are passed to the agent. Below is a sample agent:
Option Public Option Declare Use "Class.URL" Sub Initialize Dim url As URLData '*** Create new URLData object Set url = New URLData() '*** MIME Header to tell browser what kind of data we will return Print "content-type: text/html" '*** Check reqired values for this agent If url.IsValue("name")=False Then Print "Missing argument 'name'." Exit Sub End If '*** Process name argument If url.GetValue("name")="" Then Print "'Name' is empty." Else Print "Hello, " + url.GetValue("name") + "!" End If End Sub
It is that easy.
If my proposal for a session at ConnectED is accepted, you will about how to use jQuery and Bootstrap to retrieve data in .NSF databases through Lotusscript agents, and I will be using this class in my demos. So see this as a preview.
If the session doesn’t get selected by IBM, I plan to record it and post it somewhere online later.
The premise of the session is that you have data in a Domino database, but for some reason you can’t use XPages. Your company may be on an older version of Notes/Domino with no plans/budget to upgrade, the web developer don’t know XPage and have no time to learn it, or the data will be retreived from some other Web based system, perhaps WordPress.
Update: The session was not accepted at ConnectED, but I will present it at WMLUG in Atlanta on August 19, 2015.
